项目摘要

- Created a compilation of proxies for past sea level during the last interglacial (approximately 120,000 years ago) for areas in North America and Europe covered by the penultimate glaciation. I will use these constraints to create paleotopography reconstructions during the last interglacial. My role in this study was to develop the compilation methodology and to enter the data in the World Atlas of Last Interglacial Shorelines (WALIS). Published in Dalton et al., 2022, Earth System Science Data, https://doi.org/10.5194/essd-14-1447-2022- Compiled sea level constraints during the Last Glacial Maximum (approximately 20,000 years ago), including in eastern Asia. These constraints allow us to assess how much of the East China Sea was exposed, and how narrow the Tsushima/Tsugaru Straits were, to set up our climate modelling experiments on the East Asian monsoon (Gowan et al., in review, Nature Communications).- Worked on four other papers that have been accepted for publication. These papers focus on topics related to past climate change, and the evolution of ice sheets. These studies have application to my planned work on paleotopography reconstructions. Gowan et al., accepted with minor revisions, Journal of Glaciology; Hinck et al., The Cryosphere, https://doi.org/10.5194/tc-16-941-2022; Dalton et al., Global Planetary Change, https://doi.org/10.1016/j.gloplacha.2022.103814; Yang et al., PLOS ONE, https://doi.org/10.1371/journal.pone.0259816. I also have worked on three other papers that have yet to be submitted.

-为北美和欧洲倒数第二次冰期覆盖的地区创建了最后一次间冰期（大约12万年前）过去海平面的代用指标汇编。我将利用这些约束条件重建末次间冰期的古地形。我在这项研究中的角色是开发汇编方法，并将数据输入世界末次间冰期海岸线地图集（WALIS）。发表于Dalton等人，2022年，地球系统科学数据，https://doi.org/10.5194/essd-14-1447-2022-编纂的末次冰期极大期（大约2万年前）包括东亚地区的海平面约束。这些限制条件使我们能够评估东海暴露的面积，以及对马海峡/津加鲁海峡的狭窄程度，从而建立我们对东亚季风的气候模拟实验（Gowan等人，综述，Nature Communications）。-参与撰写了另外四篇论文，并已被接受发表。这些论文的重点是与过去气候变化和冰盖演变有关的主题。这些研究已应用于我计划进行的古地形重建工作。Gowan et al.，经小修改接受，《冰川学杂志》；Hinck等人，冰冻圈，https://doi.org/10.5194/tc-16-941-2022；道尔顿等人，全球行星变化，https://doi.org/10.1016/j.gloplacha.2022.103814；杨等，PLOS ONE, https://doi.org/10.1371/journal.pone.0259816。我还完成了另外三篇尚未提交的论文。
